A grain is a unit of measurement of mass, and in the troy weight, avoirdupois, and apothecaries' systems, equal to exactly 64.798 91 milligrams. It is nominally based upon the mass of a single ideal seed of a cereal. From the Bronze Age into the Renaissance, the average masses of wheat and barley grains were part of the legal definitions of ...
The fabric weight is measured in grams. In the metric system, the mass per unit area of all types of textiles is expressed in grams per square metre (g/m 2). The gram (alternative spelling: gramme; SI unit symbol: g) is a metric system unit of mass. A gram is defined as one thousandth of the SI base unit, the kilogram, or 1 × 10 −3 kg.
0.1 × ( 12 ÷ 8 ) = 0.15 grain per dscf when corrected to a gas having a specified reference CO 2 content of 12 volume %. Notes: Although ppmv and grains per dscf have been used in the above examples, concentrations such as ppbv (i.e., parts per billion by volume), volume percent, grams per dscm and many others may also be used.
The U.S. perm is defined as 1 grain of water vapor per hour, per square foot, per inch of mercury. 1 U.S. perm. = 0.659045 metric perms. ≈ 57.2135 ng·s −1 ·m −2 ·Pa −1. Metric perm. The metric perm (not an SI unit) is defined as 1 gram of water vapor per day, per square meter, per millimeter of mercury. 1 metric perm.
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
0.113 39 g Ratti ( Sanskrit : raktika ) is a traditional Indian unit of measurement for mass. Based on the nominal weight of a Gunja seed ( Abrus precatorius ), it measured approximately 1.8 or 1.75 grains [ 1 ] [ 2 ] or 0.1215 g as standardized weight. [ 3 ]
The gram (originally gramme; [1] SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one thousandth of a kilogram.. Originally defined as of 1795 as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre [1 cm 3], and at the temperature of melting ice", [2] the defining temperature (≈0 °C) was later changed to 4 ...
Sheaves of wheat: one sheaf is approximately one omer in dry volume. The omer (Hebrew: עֹ֫מֶר ‘ōmer) is an ancient Israelite unit of dry measure used in the era of the Temple in Jerusalem and also known as an isaron. [1] It is used in the Bible as an ancient unit of volume for grains and dry commodities, and the Torah mentions it as ...
